signors to Ultimo Manufacturing Corporation, Orange, N. 1., acorporation of Delaware Application August 17, 1955, Serial No. 528,9543 Claims. or. 34-99 This invention relates to a device for drying hair,and specifically to an attachment for use in conjunction with a vacuumcleaner to achieve said purpose.

It is an object of this invention to provide a hair drying device whichmay be controlled as to its rate of moisture removal.

Another object of the present invention is to provide a hair dryingdevice which may be used with a minimum of discomfort.

A feature of this invention is its novel valve structure for controllingthe flow of air through its drying chamber.

Another feature of this invention is its use of lightweight materialswhereby a minimum of inconvenience is experienced by the wearer.

The invention consists of the construction, combination and arrangementsof parts, as herein described, illustrated and claimed.

In the accompanying drawing, forming a part hereof, are illustrated twoforms of embodiment of the invention, and in which:

Figure 1 is a view in front elevation of a complete embodiment of thepresent invention.

Figure 2 is a view in perspective of the hair dryer shown in Figure 1,On a somewhat reduced scale as applied to the head of a user.

Figure 3 is a fragmentary view of one form of the valve used inconjunction with the hair dryer, in accordance with the presentinvention, somewhat enlarged.

Figure 4 is a sectional view taken on line 44 of Figure 3.

Figure 5 is a fragmentary view of a second form of valve for use inconjunction with a hair dryer, in accordance with the present invention.

Referring to the drawing, and specifically to Figure l, indicates adrying hood formed from any suitable air impervious material, such as avinyl, rubberized material, or the like, the bottom portion of which isprovided with an opening 11. An elastic member 12 is stitched around thefront portion of the opening 11, so as to enable the drying hood 10 toconform snugly to the wearers head, as shown in Figure 2.

Chin straps 13 are also provided on the lower edge of the hood 10 sothat the apparatus may be secured beneath the chin of the wearer.

On either side of the hood 10 and disposed at an angle of approximately45 with the side wall of said hood, there are provided ducts 14 and 15.The duct 15 comprises the entrance duct for the warm air, which air issupplied from a vacuum cleaner indicated at 16 in Figure 2. A smallsecuring string 17 is carried by the duct 15 adjacent the attaching endthereof, so that the said duct may be held to the nozzle 18 of thevacuum cleaner 16.

The duct 14 leads the moisture-laden air from the hood 10 and dischargesit into the atmosphere. The outlet end of the duct 14 is provided with avalve 19, best shown in Figure 3, whereby the rate of flow of airthrough the hood may be regulated. The valve 19 is constructed in amanner whereby it will permit the flow of an amount of air sufficient toprevent the hood from being blown from the head of the wearer when thesaid valve is completely closed. When completely open, the valve willpermit a substantially large amount of air to pass out of the hood.

According to the showing in Figure 3, the valve consists of acylindrical body member 20, having areduced portion 21 at the outlet endthereof, and a sleeve 22 slidably and rotatably mounted upon the saidreduced portion 21. The sleeve 22 is provided with a series of openings23, which openings may be brought into register with a similar series ofperforations 24 in the reduced portion 21 of the body of the valve 19.

A pin 25 is secured to the sleeve 22 and projects inwardly through aslot 26 in the reduced portion 21. The pin 25 secures the sleeve to thevalve body 20 and permits the said sleeve to be rotated upon the reducedportion 21, thereby regulating the size of the air passage between theapertures 23 and 24.

As set forth previously, the inside diameter of the valve 20 is suchthat when the apertures 23, 24 are out of register, a sufficient amountof air will pass through the valve to maintain the hood upon the head ofthe wearer.

In Figure 5 there is shown a second valve made in accordance with thepresent invention, employing a rotatable disc 27 which is disposedwithin the air passage of the valve body 20. The disc 27 may be securedin any position by means of a wing nut 28, or other securing device. Itis within the purview of the present invention to make the disc 27somewhat smaller than the air passage of the valve 20, so that whencompletely closed it will not cause the hood 10 to be forced from thehead of the wearer. Alternately, the disc 27 may be co-extensive withthe interior of the valve body 20, but provided with a plurality ofholes to permit a requisite amount of air to pass therethrough when thedisc is disposed normally to the longitudinal axis of the said valve.

By enabling the user to regulate the amount of air passing through thehood, the present construction makes it possible for persons havingvarious thicknesses of hair to adapt the dryer to their specific needs.In addition, the temperature of the air passing through the hood can beregulated by permitting a greater amount of air to flow therethrough, soas to carry away the moisture at a more rapid rate. I

From the foregoing, it will be seen thatthere has been provided aninexpensive hair drying device, capable of use over a wide variety ofconditions, and subject to regulation and control at the pleasure of thewearer.

The provision of the elongated duct 14, whereby the Warm air is led fromthe hood 10, adds to the comfort of the wearer in that the heatedmoisture-laden air can be expelled at a point distant from the face ofthe user.

Having thus fully described the invention, what is claimed as new anddesired to be secured by Letters Patent of the United States,'is:

l. A hair drying device for attachment to an air supply comprising, ahood formed of pliant, air impervious material, a head receiving openingin the bottom of said hood, an elastic member incorporated within theedge of said opening and adapted to yieldably reduce the size of saidopening, a first duct communicating with the interior of said hood andadapted to lead the drying air into the hood, a second ductcommunicating with the interior of the hood adapted to lead air out ofthe hood and valve means consisting of a tubular housing having aninside diameter of a size which will permit a flow of air therethroughsutiicient to insure the security of the hood upon the head of thewearer at all adjustments of the valve and having a plurality ofapertures in the side wall thereof and a sleeve rotatably carried uponthe housing, said sleeve having a seriesof apertures in the wall thereindisposed so as to be registrable with the housing apertures uponrotation of the sleeve, said sleeve and housing being carried by thefree end of the second duct to control the passage of airthrough thehoodand out of the second duct;-

2. A hair dr-ying device for attachment to an air supply comprising, ahood formed of pliant, air impervious 'ma-.

a desired minimum flow of air from the valve at all times and means tolock the said disc in a selected positionvto regulate the flow of airthrough said valve carried by the free end of the second duct to controlthe passage of air through the hood and out of the second duct.

3. A hair drying device according to claim 2, in which thedisc is of adiameter-but slightly less than that of the housing bore and providedwith perforations to insure a desired minimumfiow of air through thevalve at all times. 7
